The top ribbon doesn't stay expanded each time a new slide tab is opened

Hi TianxuanLiu,

Happy to help! I understand that the Storyline ribbon does not stay expanded each time a new slide tab is opened on your end.

I conducted some tests using the same Storyline version based on what I understood from the description. Fortunately, the Storyline ribbon remained expanded after clicking on a slide from Story view to open a new slide tab.

Please let me know if I followed the same reproduction steps you're doing. Otherwise, if you're comfortable sharing a screen recording of your experience, we'd be happy to dig deeper into this issue with you.
